Outcomes
Primary Outcome Measures
Percentage of Participants Achieving a Total Fingernail Modified Nail Psoriasis Severity Index (mNAPSI) 75 Response at Week 26
Each fingernail was assessed for psoriasis with mNAPSI, and the scores of all 10 fingernails were combined. Investigators assessed each nail abnormality for each of a participant's nails by grading 3 features or groups of features (pitting, onycholysis and oil-drop dyschromia, and crumbling) and noting the presence or absence of 4 features (leukonychia, splinter hemorrhages, hyperkeratosis, and red spots in the lunula). The range of possible scores was 0 to 130, with a score of 0 indicating absence of nail psoriasis and a score of 130 indicating the most severe nail psoriasis. A decrease in mNAPSI score indicates improvement. The mNAPSI 75 response is defined as at least 75% reduction from baseline in mNAPSI.
For United States (US) Regulatory Purposes: Percentage of Participants With a Physician's Global Assessment of Fingernails (PGA-F) of "Clear" or "Minimal" at Week 26
The PGA-F is a 5-point scale used to assess fingernails separately for nail bed signs and nail matrix signs of disease. A global score of between 0 indicating clear, and 4 indicating severe, was separately assigned for nail bed involvement and nail matrix involvement. A participant's overall global score was the worse of the nail bed and nail matrix score. Data presents the percentage of participants with a PGA-F overall global score that met the definition of "clear" (0) or "minimal" (1) with at least a 2-grade improvement relative to Baseline at Week 26.

Each dimension comprises 5 levels with corresponding numeric scores, where 1 indicates no problems, and 5 indicates extreme problems. A unique EQ-5D-5L health state is defined by combining the numeric level scores for each of the 5 dimensions and the total score is normalized from -0.594 to 1.000, with higher scores representing a better health state. An increase in the EQ-5D-5L total score indicates improvement.
